Thread: Myford solutions
25/05/2019 19:53:28

I made an order with Myford solutions about three weeks ago and nothing has arrived yet. Email has not yet been responded too either. It looks legit but I am starting to get suspicious.

Has any one had any experience with them?

Thread: ML7 Carriage shims and wear
03/05/2019 18:04:01

I stripped the carriage for cleaning, (all full of iron chips) and noticed grease had been used, which I understand is bad.

But what really vexed me is that after cleaning and oiling, when reassembled, the carriage locks up solid when the screws at the front are tightend.

It is shimmed front and rear, is it possible someone had used shims to thick?

They don't look like plain brass except were it appears to have worn through the grey coating on one.

The screws holding the front retaining strip were a bit too easy to remove and I wonder if they had been used to adjust play.

This makes me wonder about wear and how to measure how worn parts are.

Thread: ML7 feed screw wear
26/04/2019 00:45:30

Having got an understanding of Gib strips and correct set up, I noticed my cross slide and compound slide feed screw nuts are worn, the cross slide has a little play and the compound quite a lot.

Can I replace the nuts and be ok, or must the screws be changed as well?

Would the Arc Euro Trade bearing mod fix things cheaper?

Thread: ML7 compound slide setup
02/03/2019 15:20:53

I have been wondering what to do with the four grub screws on the compound slide since I took it off to put the quick change tool post from Arco. There is a metal wedge bit inside I presume to take up slack from wear.

Before I took it off I found the compound handle was hard to turn with a tight spot. Is the a secret to adjustment to get it set up nicely? Maybe an upgrade?

Thread: ML7 questions

Ohh this is good! I saw that on an end before but did not know it could be done this way too.

I rummaged through all the bits in the box that came with the machine and found what looks like a home made height gauge. Need to calibrate that too.

Posted by clivel on 06/12/2018 22:28:02:

There are a few ways that a lathe tool can be set to centre height.

One way is to face the end of a piece of metal held in the chuck. If a pip remains, the tool is not at centre height. Retract the tool, turn off the lathe, adjust the tool either up or down by about half the pip diameter and try again until no pip remains.

Alternatively you could use a steel rule trapped between the tip of the tool and the workpiece. With the lathe off, hold the rule vertically against the workpiece, gently (so as not to damage the rule) feed the tool in trapping the rule between the tip of the tool and the workpiece. If the rule leans towards the back of the lathe, then the tool is too high, if it tilts forward then the tool is too low, the rule will be vertical when the tool is at centre height .

You could also consider making a centre height gauge. Not only would you end up with a useful tool, but could also be a worthwhile learning experience. Geo Thomas described such a gauge in the "The Model Engineers Workshop Manual" a book well worth seeking out. Hemingway also do the gauge as a kit seen here

Thread: Sourcing

Don't know where to start.

Are there scrap yards for bits?

Any tips for sourcing useful bits of metals for cheap or free?

Thread: ML7 questions
06/12/2018 20:14:15

Is there a guide to centering tools to workpiece using a quick change tool post?

I guess the same would apply to using a DTI at initial setup in a tool post?

There is a picture of a DTI in use in the manual but I could not find a device to hold it, not of the shelf.

Thread: ML7 Quick change suggestions
23/11/2018 20:59:31

Its a matter of skill, you have it, and I don't! crying Later on it would be cool though.

I don't want to buy junk. I have found the 000 model and adaptor on ARC website, and the 'official' Myford one.

23/11/2018 20:00:53

I am looking to buy a good quick change tool post for the ML7, not too sure about RDG or Chronos stuff.

What is a good one to choose?

Thread: Drip oiler question
06/06/2017 20:58:05

Thank you, had to be sure. Made assumptions before, and they were not always right...

Thread: ML7 VFD parts
06/06/2017 19:47:21

Has anyone installed a VFD on their ML7?

I understand a three phase motor is required, do they have a recommended parts list?

Cheap/used is OK.

Thread: Drip oiler question
06/06/2017 19:30:11

I need to fit a replacement drip oiler the the ML7. Its the right thread, but sits to high to screw down on its seal. Does that matter? It sits over the bearing its meant to lube, so surely its going to work?

Thread: Help with dismantling solid riveted lathe stand
11/06/2012 16:30:14

I have measured the width of the window and I should have 1/4'' each end to fit it through. The place is rented and despite a so called preservation order, its in a terrible state of repair and barley holding together. I dont fancy dismantleing any part of this house even with permission, as I dont trust it isn't bodged in the first place.

If I go with through the window, I will probably have to do a bit of covert night ops as the only sash window left is the one overlooking the main road through the village. The path is narrow here so anything you haul up will be suspend over passing traffic, and might look a little suspicious.

Not possesing a 5mm punch I have one on order, just in case I go that route. I will post victory pics when done. Or just move house (planning that anyway) to somewhere with a proper workshop away from noisy roads.

Having just received my ML7 and got it upstairs (nothing ruptured) the next problem is how to get its custom made stand up an angled Victorian staircase.

I thought it would be be simple, but nooooo, it wont fit and is extremely well made and very rigid.

Having removed the bolts to remove the top I found what looks like solid rivets under all the paint.

Rivet join

Another shot
Bolt hole
I reckon if I can get the top off I get get it 'around' the stairs and then re-attach upstairs.
I don't want to ruin it, so what should I do? Feebly attempt to knock them out? Drill?
Thread: Starting out and choosing tools
09/06/2012 18:29:47

Thanks for all your replies. I have bought a really nice looking Myford ML7 with some tools including a vertical slide. I think I got a lot for the money! If for some reason its not what I want (unlikely!) I am confident that I would get back at least what I paid for it.

I bought it from a gentlman at who used it to build O gauge locomotives, and apparently has had a good pedigree of similar carefull owners.

The one problem now is how to get its custom built stand up the stairs...I will start a new thread for that.

01/10/2011 03:02:17
Please can someone tell me what I should be looking for with regards to a drill press, a lathe and a mill, or anything else I might need? I know a tool collection has to grow, but where do i start?
I must point out that I dont really know the correct terminology of most machine tool parts (not having touched anything since school long ago) and am likely to get lost in jargon.
I mostly want to be working in up to 16mm scale narrow gauge model railways, model aircraft engines and eventually motorcycle engines. I suppose you could say general light engineering.
 
Any tips on where to buy stuff would be a great help too.
